Abstract:
Objective To evaluate the urinary iodine detection ability of Iodine Deficiency Disorder Laboratory in Shaanxi Province,and to test the quality of laboratory construction.Methods In Shaanxi Province,ten city-level and 107 county-level urinary iodine labs of Center for Disease Control and Prevention or Institute for Endemic Disease Prevention and Control were selected in 2018,and two urinary iodine quality-control samples were measured by As3+-Ce4+ catalytic spectrophotometry.The results of urinary iodine quality control were evaluated through standard Z score generated from all the participatory labs.Results All 117 labs had feedback their testing results.There was one lab with an inter-laboratory |Z| score≥3,and 3 labs with inter-laboratory |Z| score≥3,and the qualified rate was 96.58% (113/117).In 107 county-level urinary iodine labs,there was one lab with an interlaboratory | Z| score ≥ 3,and 3 labs with inter-laboratory | Z[score ≥ 3,and the qualified rate was 96.26% (103/107).Conclusions The construction of urinary iodine lab has achieved great results in Shaanxi Province,the testing ability of iodine determination laboratory is maintained at a high level,which has laid a solid foundation for prevention and treatment of iodine deficiency disorders in Shaanxi Province.
